a dayt apple fell below $400, now at 31.66 on the nasdaq composite, and the s&p down ten-plus points at 1541, and we are just moments away from earnings from the big three, ibm, microsoft, and google. we have them all covered for you. david garrity from gba research. >> wow. >> yeah, we're back on "power lunch" days. >> is that an octabox. >> jon fortt, josh lipton. first, heather hughes and rob malcolm, along with greg ip "the economist." everybody's in the water, so we can just jump in. heather, what do you make from the markets this week? what's the message from this very volatile market in your view? >> well, the markets have picked up volatility. before last week, the vix volatility measure was at all-time lows, since 2007. that, of course, has increased, but it will be interesting when we get these earnings numbers coming out now. of course, corporate profits, that's key. it seems like it's coming from revenue minus costs, we're cutting cost sides of the equation, not necessarily revenue and topline growth. it so will be interesting to see what those numbers are as we get them.
